Design Of Smart Home Security System

With the improvement of economic level, people’s material life and spiritual life has been greatly improved, and in good condition of modern science and technology progress rapidly, smart home systems caught the attention of the professionals worldwide, related to the research of "is also in full swing.Smart home system with Internet communication technology, computer technology and electronic technology as the foundation, combined with the related principle of human body engineering, based on the actual needs of users, all related to household life subsystems organically linked, including lighting control, floor heating, security, home appliance control, etc., using the Internet and computer to realize intelligent control, so as to give the user more human operating experience, enjoy the high-tech household life.In smart home system is designed in this paper, the overall use "system control center and Zigbee wireless sensor network", the paper of different chapters respectively introduces the design idea, part of the framework and system solutions.In building a family monitoring network, this system mainly using Zigbee technology, and design the relevant network node application, the design of system control center for the PXA270 processor types, connected by establishing and processor module, so as to receive signals from the home network, and using GPRS module to realize the early warning mechanism as well as the information transmission and circulation.The intelligent household security system designed by the authors, the system control center controller for the PXA270, support for multiple interfaces, expand the use of space, and Zigbee sensor network to test the household environment, at the same time the ability to connect different sensor terminal, so as to realize the circulation and transmission of data, within the maximum saves the cost of data transmission...
